Life‐cycle theories emphasize the fact that consumption is allocated intertemporally, on the basis of a long‐term concept of resources that differs from household income. Because life‐cycle income is unobserved, the distribution of this variable cannot be recovered. It is shown that, within a suitably defined class, a predictor of life‐cycle income based on household income and expenditure entails a distribution dominated in a social welfare sense by the distribution of life‐cycle incomes. A predictor constructed from socio‐demographic variables induces a distribution that welfare‐dominates the distribution of life‐cycle incomes.
